Hi all - I have been using an Amazon Paperwhite for years, and am considering a Glight PLus for a second reader. My question is about library books via OVERDRIVE - can you get them over WiFi like Amazon delivers them, or do you have to download them onto a computer and then transfer via USB Cable? Also, can you put it in "Airplane Mode" so as to keep the borrow from expiring until you finish it, like the Kindle? Thanks!
